On February 10 1951 a US Navy flight, Atlantic - Continental Air Transport Squadron one, located at USN Air Station, Patuxent River, Maryland, was out of Keflavik, Iceland at 49-50 degrees north latitude and 50-03 degrees west longitude about 150 kilometers 90 miles west of Gander, Newfoundland out over the Atlantic Ocean. The aircraft was probably bound for Gander to refuel judging by its position and course of 230 degrees true, though the report does not mention this. US Naval Reserve Lieutenant Graham Bethune, co-pilot of Flight 125, was occupying the captain's seat on the left side of the cockpit in the passenger plane when he first sighted a huge UFO at least 300 feet in diameter on a near collision course with their aircraft. The co-pilot stated in his official report,... I observed a glow of light below the horizon about 1,000 to 1,500 feet [330-470 meters] above the water. We both the pilot as well observed its course and motion for about 4 or 5 minutes before calling it to the attention of the other crew members.

Suddenly its angle of attack changed. Its altitude and size increased as though its speed was in excess of 1,000 miles 1,670 kilometers per hour. It closed in so fast that the first feeling was we would collide in midair.At this time, its angle changed and the color changed. It then appeared definitely circular and reddish orange on its perimeter. It reversed its course and tripled its speed until it was last seen disappearing over the horizon. The co-pilot's report goes on to say that the UFO came within five miles of their aircraft which was borne out by radar evidence of the encounter because the UFO had been tracked by DEW Line Ground Radar at the base in Goose Bay, Labrador.
